Research Project: Developing and Promoting Water-, Nutrient-, and Climate-Smart Technologies to Help Agricultural Systems Adapt to Climate and Societal Changes

Location: Soil, Water & Air Resources Research

Project Number: 5030-11610-005-45-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Mar 1, 2015
End Date: Feb 28, 2019

Objective:
1) Evaluate the factors limiting water use and nutrient use efficiency in corn production systems and implement these practices to promote climate resilience; 2) Determine the potential adoption of impoved water and nutrient management practices through grower evaluation; 3) Evaluate using crop simulation models and the potential of long-term impact of improved technologies and stabilize corn yields under climate change; and 4) Develop educational materials for transfer of information to producers on climate-smart technologies.

Approach:
Detailed studies will be conducted on corn production systems in the upper Midwest to determine their water and nutrient use efficiences under different management scenarios. These data will be compared to the results obtained with crop simulation models predicting crop growth and yield. Data collected over these experiments will include energy balance and remote sensing observations at the plot and field scale to define the temporal and spatial variation and how these data can be utilized to improve crop models. Crop simulation models will be utilized to estimate the potential impact of climate scenarios and the most effective management practices to achieve climate resilience.
